Question

$\sqrt3{1331} = \square$

Explanation:

Step1: Recall cube of 11

We know that \(11\times11\times11 = 11^3\). Calculate \(11\times11 = 121\), then \(121\times11 = 1331\). So \(11^3=1331\).

Step2: Apply cube - root definition

The cube - root of a number \(x\) is a number \(y\) such that \(y^3=x\). For \(\sqrt[3]{1331}\), since \(11^3 = 1331\), by the definition of cube - root, \(\sqrt[3]{1331}=11\).

Answer:

\(11\)
